Even oopses have pitfalls, like in 25-rcs where those WARN_ON TCP 
backtraces were due to three different bugs (there might be fourth one 
still remaining). ...kerneloops.org didn't even make difference between 
different WARN_ONs in a function though that would have helped only little 
in the case of 25-rc TCP because of different bugs causing failures in the 
same invariant.
